He is one of the villagers you can talk to get trading sticks in exchange for doing work around the village in the Tai Bwo Wannai Clean Up Mini-game. You can also ask him to make a gem bladed machete for you. He can make an Opal machete, Jade machete, or Red topaz machete. Depending on which you want, it will cost you various amounts of trading sticks, specific gems, and a gout tuber. When you ask him to make you any of the machete, you will also complete a medium task in your Karamja Achievement Diary.
